IGNITION DISTRIBUTOR Application filed December 26,1923. Serial No;682,716.

This invention relates to a distributor for electrical current and asillustrated is par ticularly adaptedfor use in the distribution ofignition current to the various cylinders of an internal combustionengine.

Theprincipal object of my invention is to providea distributor for amulti-cylinder engine, to which the cables may be quickly attached withthe least amount of work. It is another object of my invention toprovide a distributor which is relatively simple in construction yeteiiicient in its operation. 7

Other objects will be apparent to one skilled. in this art after a studyof the drawings taken in connection with the specification.

In the drawings:

Figure 1 is a plan view of a distributor with the cover removed,

Figure 2 being the inner part of the cover fitting over the distributorshown in Fig. 1.

Figure 3 isa sectional view on the line 3/3 of Fig. 1 but with the coverand other parts in position.

Figure 7 is a plan view of the rotating distributing member shown inFig. 4.

Figure 8 is a side view of Fig. 7 v

Figure 9 is a fragmentary sectional view on the line 9/9 of Fig. 1. f

Figure 10 is a fragmentary plan view similar to Fig. 1. but of thedistributor block shown in Fig. l with the cover re moved.

Referring to the details wherein like numbers refer to correspondingparts in the various views, 1 is a supporting member in which a pair offrictionless bearings 2 are positioned for the purpose of carrying anv Qoperating shaft 3. In Fig. 4 a plain bearing 4 is used instead of theball bearings shown in Fig. 3. Carried on the stubv shaft 3 is a collar5, the same being held there in any suitable manner as by nut 6. To thecollar 5 is attached a distributing member 7, the same being heldto thecollar 5 as by screws 8 only one being shown in the sectional viewFig.3. The distributing member 7 is ofv any suitable insulating materialand preferably moulded thereimis an insert 9, having a centrally locatedcontact 10. To therinsert -9 is attached a main contact terminal 11, as

by means ofa screw 12.

Thesupport member 1 is fastened to some part of the engine casin as bymeans of a suitable number of screws 13. Carried on the support member 1isa blockof insulating material 14:, which is held to the member 1 inany suitable manner as by screws 15. The block 14 has a number ofsubstantially radially arranged recesses or channels 16, which aredeeper toward the edge of the block and slope or taper upward toward thecenter thereof as is clearly shown in Fig. 3. In the deeper part of eachof the channels 16 is positioned a contact 17sh0wn in the form of astiletto pin. This pin is. securely fastened to a plate 18 and the twotogether are preferably moulded integral with the block 14. There is anopening through the bottom of each channel and positioned in thisopening is an ignition pin 19. which in the form shown is arranged sothat it can be riveted to the plate 18 after the block has been moulded.I prefer this arrangement because of the large number of-pins 19projecting downward in opposite direction from the stiletto pins 18.makes the withdrawal of the whole block from the mould diflicult. as thelower projecting pins are likely to be bent.

Therefore. I have constructed the block so that the ignition pins 19 maya separate operation.

The channels 16 are of such depth that the high tension electricalcables 20 lying therein will be forced downward over the stiletto pin17, which thereby makes contact with the conductors 21 and at the sametime the cover 22 will press against the upper surface of the cable 20and hold it securely in pobe put in as sition in the channel and overthe pin 17.

This holding action of the cover on the cables is improved by means of aseries of ridges 23 moulded in the cover. The cover in Fig. 3 has acentral opening 24 through which all of the cables lying'in the channel16 may pass. In addition a centrally located cable 25, coming from theignition coil or an igni tion magneto, is attached to a-nfinsert 26through the medium of a wood "screw 27, it being understood that thestrands of the conductor 21 pass through little iri'ith'e the auxiliar3source oi starting current to one of the studs which 18 used torhcilding the cover to the distributor block.

hown riticularly in Fig.

. nected to the stud ion may be indicated by The distributor '1' qdotted men do p05 line shorm. in Fi T as shown carries an annular 83, chis adapted. to cooperate with the contact and the is connected by meansat a conductor "i (see Fig. (I) to an ignition pin tl at is in the sameplane w th. contact ll... but set at. an angle trailing behind the maincontact ill. (see The parts 3 and 3:) are shown in dotted position inFig. but at an angle oi apl'n'oxiiuatcly 180 degrees tor the purpose otclarity. The purpose of the trailing brush is to allow the startingignition current to be applied to one of the work ng; cylinders at atime utter the given piston has gone over compression.

In order to prevent the starting ignition current :trom jumping from theannular ring; 83 to any part; of the metal. support member 1, I providea. barrier 36 which in the iiorm shown in Fig. 3 is an insulating discbut in Fig. t it is the bottom of the distributor block. It will bereadily obse wed that the pin 82 may be placed in the member 7 and theannular ring may be placed in the distributor block as is sho 7m n Fig.=1. In this particular figure the distributor block is made in twosections 37 and 38, the upper section 37 being; constructed so that itmay be rotated with respect to the lower section and the distributormember 7 for the purpose of adjusting; the gnition pins 19 with respectto the main distributor contact 11, after wuich adjustment has beenperformed. the section 3'7 is locked by means of a screw 39 passingthrough one of the studs 31 into engagement with. the serrations 40which may be moulded in the section 37 (see Fig. 1.0). This adjustmentis observed through a peep hole c'orered by a piece 0t. non nliammableinsulating material, such as mica illustrated by the numeral 4-1 (Fig.8).

In the forms shown, the distributor is what is known to the trade as thejump spark type, rather than the wipe contact type.

The cables instcad ot leaving the distribulor tron! the ccntcr in Fig.-l. lcare he block radiall; and the holes 12 through tl c hloclr ii "forSflCllllllg the pins 19, are some that deeper than in Fig. 3: Also thecable 30 from the starting ignition source is attached to the ring 33 ina 7 dilicrent manner than in Fig. 3. l. be a p arcut that variouschanges made in the detailsv without departt ot my intention and the "tthe appended claims. .lla'rinp' thus described my invention. what Iclaim is:
